For international professionals evaluating sole proprietorship options in Spain in 2025, the available legal status is the Autónomo (Trabajador Autónomo). Below, you’ll find an in-depth overview of the status’s availability, requirements, and financial obligations under Spanish law, focusing on practical data sourced from official government channels.
Autónomo (Sole Proprietor) Status in Spain: Availability and Access
Spain offers a straightforward individual business status through the autónomo regime. This pathway enables any individual to operate commercially, invoice clients directly, and fulfill tax obligations without the creation of a separate legal entity. Registration is open to regular citizens and widely used among local and foreign residents alike.
Key Steps & Registration Requirements
- Spanish Tax Agency (Agencia Tributaria) Registration: Required to declare the start of economic activity.
- Social Security System (Seguridad Social) Registration: Compulsory for all autónomos to access the Spanish health and pension system.
The process is considered simplified compared to many legal corporate forms, with most steps handled online or directly in-person at the respective government offices.

Mandatory Taxes and Contributions Explained
Income Tax (IRPF): All sole proprietors pay personal income tax on the net profit generated by their business. Spain employs a progressive scale from 19% to 47%. Actual liability depends on total declared income, with higher net earnings taxed at higher marginal rates.
VAT (IVA): Standard VAT on most goods and services is 21%, with exceptions for certain activities subject to reduced rates. Registration for VAT is compulsory if you invoice clients for taxable activities.
Social Security Contributions: Autónomos are required to make monthly contributions to the social security system. The minimum monthly base for 2025 is €950 ($1,026), leading to a minimum monthly payment of around €230 ($248). Actual payment scales with your declared income.
New Autónomos Discount: The “tarifa plana” or flat-rate regime allows newly registered autónomos to pay a simplified, lower social security contribution for the first year of activity, making market entry more manageable.
Comparison: Advantages and Practical Impacts
The autónomo status is the main legal route for individuals aiming to invoice clients directly in Spain without the complexity of company formation. Its key advantages include ease of setup, direct responsibility for taxes and social security, and accessibility for both locals and foreign residents. However, Spain’s social contributions and progressive income tax rates should be considered in business plans, especially compared to other European frameworks.
